I just bought Sonic port VX and connected to my Ipad mini and on the other side to power supply and Ipad saying: "don´t charge". I tryied different cables from power supply to sonic port but without change.

When you plug in and wait a few seconds the "not charging" should change to the charging (lighning) symbol. If it does not you might have a bad cable and the best way to resolve this would be to contact our customer support.
